Maize ear rot
Mould on maize cobs, often after rain at harvest. Mouldy grain is unsafe to eat.

What it looks like

Every field looks a little different. If you are not sure, ask in the app’s Farmers, or ask an agronomist.
When it comes
| Crop | Stage | Check |
|---|---|---|
| Maize | Grain fill | Scout weekly |
What to look for
Once a week, pull the husk off a few cobs and look. If grains have holes, dark spots, or look mouldy, harvest sooner — waiting only makes it worse. Walk the edges of the field for rat trails or burrows; rats can ruin a corner of the field overnight.
Also watch for
General advice from crop guides for Ghana. Before you spray, ask your agro-input dealer for a product registered for this pest, read the label, and wear gloves. For a serious attack, call your district agriculture office or an agronomist.
